Boathouse 4 inch 3 ton block with ball bearings

The 4″ 3 Ton Ball Bearing Block is simply the best block available for any overhead lift application requiring blocks. The hot-dipped galvanized coating far exceeds the standard zinc plating found on most blocks.

Maintenance is easy with the easy-to-reach grease fittings and ball bearings that eliminate friction. The breakaway shackle allows for easy replacement or installation without having to uninstall the cable. The raised stamp rating also meets industry rating requirements. The ball-bearing blocks only weigh 6.1 lbs and ship directly from BH-USA.
